Only PA-sited solar facilities are eligible to earn SAECs.

Systems located outside of Pennsylvania but within the PJM interconnection footprint may qualify for Tier I AECs if they derive energy from the following: solar photovoltaic and solar thermal energy, wind power, low-impact hydropower, geothermal energy, biologically derived methane gas, fuel cells, biomass energy, or coal mine methane.

A system may qualify for Tier II AECs if it is located in Pennsylvania and derives energy from the following: waste coal, distributed generation systems, demand-side management, large-scale hydropower, or municipal solid waste.
